As I sit here considering my upcoming performance for the TNO at Kenny's Castaways (4/21), I'm thinking of how to simply and effectively back myself on stage. That is to say, how can I alone influence a backing track or tone that follows not only the notes I'm playing but also the rhythm?
I've seen shows (well, openers for shows) where the musician strums along to an MP3 playing in the monitor. It's a cute notion, sort of playing along to your own song. But what I have in mind is something reliably maleable - it doesn't exist before you begin playing and it dies out after you stop. It's a bit like reverb but it exists a half second before you play the corresponding note. And herein lies the mystery: how to have the computer anticipate your sound and rhythm.
Though I've only just begun pondering this, my first thought is to allow a significant delay in the monitor. This delay would allow the computer (or effects pedal - whatever it may be) to process the sound from the previous second or 2 and slide out it's results a fraction of a second before the musician's input is broadcasted to the speakers.
Yes / No? Probably no.
